So then all the networks that have done $things to BitTorrent to demote it
to second-rate traffic will suddenly have a bunch of very angry Apple fans
whose downloads are mysteriously having issues.
And then - assuming you intend for more things than just Apple to go this
route - all the CDN's would need to be redesigned to support BT too.
It seems like it'd be simpler for Apple to figure out how to validate a
partial download and then resume. It isn't like that would be cutting
edge technology. I think I might even have seen it happen before.
